    Cosmic dust consists of tiny particles of solid material floating around in the space between the stars. It is not the same as the dust you find in your house but more like smoke with small particles varying from collections of just a few molecules to grains of mm in size. Dust is important because we find lots of it around young stars.

    Cosmic dust is submillimeter debris shed by comets, asteroids, moons, and planets. These small particles are the largest source of extraterrestrial material accreting on the present-day Earth.

    The Cosmic Dust Analyzer, or CDA, detected dust particles one-thousandth of a millimeter wide (the size of smoke particles) and sometimes as small as one-millionth of a millimeter (smaller than a virus). As a dust particle entered the CDA, the instrument determined the particle's charge, speed, size and which direction it was going.

    Apr 17,  · Dust is found throughout the plane of the Milky Way. The dust particles are about the same size as the wavelength of light and consist of rocky cores that are either sootlike (carbon-rich) or sandlike (silicates) with mantles made of ices such as water, ammonia, and methane.
